A temperature control system uses electrohydrodynamic heat transfer enhancement effects. By applying an electric field across a heat transfer fluid, the heat transfer coefficient can be controlled as a function of the applied voltage. This effect can be used to control the amount of heat energy transfer from one fluid to another fluid. By controlling the heat energy transfer, the discharging temperature of the fluid can be controlled. A heat exchange device (11) may include two chambers (13, 15) each having a fluid inlet (17, 19) and a fluid outlet (21, 23). A liquid isolating, heat conducting barrier and common electrode (25) separates the chambers. Fluid is conveyed to the chambers in generally opposed directions to cause the fluids to flow in opposite directions near the surface of the barrier (25). The temperature of one fluid is sensed by a temperature sensor (27) after the one fluid passes from one chamber outlet (21) and the electric field is applied to at least one of the fluids to enhance the rate of heat transfer between the two fluids and achieve the desired temperature of the one fluid.
